By the best selling author of The Selfish Gene 'This entertaining and thought-provoking book is an excellent illustration of why the study of evolution is in such an exciting ferment these days.' Science 'The Extended Phenotype is a sequel to The Selfish Gene ...he writes so clearly it could be understood by anyone prepared to make the effort' John Maynard Smith, London Review of Books 'Dawkins is quite incapable of being boring this characteristically brilliant and stimulating book is original and provocative throughout, and immensely enjoyable.' G. A. Parker, Heredity 'The extended phenotype is certainly a big idea and it is pressed hard in dramatic language.' Sydney Brenner, Nature 'Richard Dawkins, our most radical Darwinian thinker, is also our best science writer.' Douglas Adams 'Dawkins is a superb communicator. His books are some of the best books ever written on science.' Megan Tressider, Guardian 'Dawkins is a genius of science popularization.' Mark Ridley, The Times


















preferred by the caddis gene, would be discussed. There might be some reference to the fact that a convenient and economical way of secreting calcium carbonate involves the use of a snail. But, from the gene’s-eye viewpoint, I suspect that the concept of parasitism would be treated as irrelevant. All three genes might regard themselves as parasitic, or alternatively as using comparable levers of power to influence their respective worlds so as to survive. The living cells of the snail would be

the harmony might have come about through Model 2’s frequency-dependent selection. In any given area, historical accident determined that there was an initial majority in favour of one colour type or the other. In an area that happened to be dominated by pink cicadas, blue ones were penalized. In an area that happened to be dominated by blue cicadas, pink ones were penalized. In both cases, simply being in the minority was disfavoured, because a member of the minority type was, by the laws of

bring a female into reproductive condition, what could he do? He does not have a syringe to inject hormones. He cannot switch on artificial lights in the female’s environment. Of course what he does is sing. The particular pattern of sounds that he makes enters the female’s head through her ears, is translated into nerve impulses, and bores insidiously into her pituitary. The male does not have to synthesize and inject gonadotropins; he makes the female’s pituitary work to synthesize them for

subject of the first part of the next chapter. 9 Selfish DNA, Jumping Genes, and a Lamarckian Scare This chapter will be a somewhat miscellaneous one, gathering together the results of my brief and foolhardy incursions into the hinterlands of fields far from my own, molecular and cell biology, immunology and embryology. The brevity I justify on the grounds that greater length would be even more foolhardy. The foolhardiness is less defensible, but may perhaps be forgiven on the grounds that
